' OF BROOKLYN, NEW YORK MANUAL SYRINGE Application filed November 11,1925. Serial No. 68,472.

This invention relates to bulb syringes of the type which are usedmanually for hygienically cleansing the vaginal canal.

Another object of the invention is the provision of means with thesyringe for introducing into the vaginal canal of medicinal substancesfor disinfecting the mucous mem brane and the allied parts thereof.

6 Another object of the invention is the provision of means which areprovided with special features for spraying a medicament into thevaginal canal and, with the cooperation of a member associatedtherewith, the

. return of flow of the injected disinfectant is prevented at will andthe anatomical parts are desirably dilated and medicinally treated andnourished, and when desired the contaminated medicament is permitted toreturn from the vaginal canal into the springe by the physical suctioncreated by the removal of pressure upon the syringe previously appliedthereto for operating the means.

The main object of the invention is, in a sense, to improve the devicedescribed in the gaspecification of application Serial No. 5653,

filed J an. 29, 1925.

To the attainment of the foregoing, the invention consists in theimprovement as hereinafter described and definitely claimed. In theaccompanying drawings, forming a part thereof- Fig. 1 is a sideelevation of a vaginal. syringe;

Fig. 2 is a side elevation of the syringe in a modified form;

Fig. 3 is a cross section of Fig. 2 taken on the line 22 as indicated bythe arrows; and

Figs. 4 and 5 are parts of Fig. 1, shown in longitudinal section.

For the purpose of developing useful fea' tures of means for simplyintroducing an antiseptic into the vaginal canal of a human vbody fortherapeutically treating the anatomical parts thereof, I provide twoconstructions shown respectively in Figs. 1 and 2, one being of amodified form. Each construotion comprises a medicament container 6having projected the sturdy elbow nozzle 7. The portion 8, comprisingthe tip part, is preferably conical in shape and provided with asuitable contact surface one for securely retaining the air container 9and the other for securely retaining the air container 10, each of whichassuming a corresponding conical contour. The nozzle obviously isprovided with a through canal 11 for passing of the liquid antisepticinto the vaginal canal from the medicament container 6.

The air container of the construction shown in Fig. 1 is provided withassociated members 12, 13, 14 and 15, which comprise an elastic bulb 12interconnected with an elastic tube 13, a check member 14 fixed in thecontainer and a release member 15 also fixed in the container, for auniform co-operation of operation of the construction as hereinafterdescribed.

The member 14 which interconnects the air container 9 with the tube 13,encloses a plunger 16 resiliently controlled by a spring 17. Thisembodiment permits the passage of air through the tube 13 to theinterior of the air container 9 when the bulb 12 is operated, v andprevents the back flow of the air from 7 the air container, whereby theair container is retained inflated with the cooperation of the member 15which is permanently fixed in the air container as hereinbeforedescribed and encloses a slidable piston 18 having its head 19 engagedon the inclined surfacev 20 thereof, thereby preventing the accidentalescape of air from the container,

The construction shown in Fig. 2 comprises a modification, which may beprovided with the check member 14 hereinbefore described for inflatingthe air container 10 in any preferable manner, to have the containerremained permanently inflated. In this manner of construction Ieliminate the elastic a al bulb 12 and tube 13 used in connection withthe construction shown in Fig. 1, but I may use the release member 15hereinbefore described, in connection with the air container 10 for theobvious reason of releasing the excessive supply of air therein. The aircontainer if desired may be hermeticall kept inflated instead of havingit inflated by the means hereinbefore described. It is also desirable tobe understood that the air container may be substituted by cushioningmeans s ch as by spongy or similar elastic means 0 the shape that willserve the desired purpose.

U insertion into vaginal canal of the nozz e the conical air containerplugs the orifice thereof and the medicament container is compressedmanually to force the liquid medicament therein through the conicalnozzle into the vaginal canal thereby filling it to the extent such thatthe anatomical parts thereof are desirably stretched and the liquid isretained therein, thus preventing premature return of the liquidtherefrom, for therapeutically feeding the anatomical parts. Uponremoval of the pressure on the medicament liquid container physicalsuction is then created by the resiliency or elasticity of the containerwhile assuming its normal contour, whereby the contaminated liquid iscaused to flow hack into the container, and upon releasing the releasevalve the air container is deflated and the construction is removed. Itis obvious, with the described construction no douche pan is necessaryto receive the returned flow of the injected liquid as in the case withthe ordinary bulb or fountain springe where such utensil is essential toreye'iit soiling the clothes or getting wet, as it may be the case.

As the ph siological or patholo ical existence of fods or ockets in anda out the mucuous membrance 0f the vaginal canal. scientific ap licationof medicament to the parts thereoi meets with many adverse con? ditionswhereby the diseased, or other, anatomical arts are not thereapeuticallybeneied for t e la .fpi' p i adm n s ra of medicament, the atter, underthe ordinary course of douching the va inal canal for treating itsparts, cannotreac its destination because, f or instance, of relapse ofthe parts ther in able c e me hich m a detriment to the roperapplication of a medicement. Exciu ing the pathological conditiop, thereexists a physiological or periodical condition which re ires hygienicirrigation of theparts, hereiiibefore described, and in this c ase proer introduction into the vaginal f a hygienic medicament is likewisemet, disa pointlments for the same 0bvioils, reasons, lierein eforedescribed,

W'ih he ab v xi t ng on i i h flow of medicament does not reach itsintended QWRE QH nd, wing o gravity, re s the moment it is introducedinto the vaginal canal, for the physical conditions of the anatomicalparts scantingly receive and cannot retain a lar er quantity of fluidthan is normally, usuafiy injected thereinto, and, as a result, theanterior and lateral parts are unsatisfactorily thereapeuticallyirrigated.

As it is obvious that with the cushioning features of the air chambersas well as with the conical shape of each nozzle, the elements form anobstruction to the return of the flow of the medicament upon theirinsention into the orifice of a human canal, and, cons uentl it causesan accumulation of the in ected fluid into the thus plugged canal uponthe application of pressure to the medicament container, to the extentof sufficiently dilating the anatomical arts, which condition permitsthe antisetp c to reach and treat all parts which have previously beenobscured owing to the conditions, hereinbefore described. Upon releasingthe pressure on the l quid container, the contaminated antise tie sreturned by suction into the or una contamer, the fluid bein then emptieand the container sterilized )1 further use. With the disclosedproperties of the elbow conical nozzle audits ail container, as well aswith the other disclosed onstructions, I provide novel means for thoroulily irrigat ng the human canal and, in a lition, e minating the use ofthe ordinary douche an. desire it to he understood that modificat ons,changes and variations may be made, as the pri ciple of the inventionresides n the novel coni bi ation of means for sy n ing the anatomiczilparts while dilating an keep ng the parts dilated under the pressure ofthe in ected fluid.
